>         Attachments: HDFS-13389-HDFS-7240.001.patch
> Currently all the Ozone/HDFS/Cblock proto files are compiled using proto 2.5, 
> this can be changed to use proto3 compiler.
> This change will help in performance improvement as well because currently in 
> the client path, the xceiver client ratis converts proto2 classes to proto3 
> using byte string manipulation.
> Please note that for rest of hadoop (except Ozone/Cblock/HDSL), the protoc 
> version will still remain 2.5 as this proto compilation will be done through 
> the following plugin.
